Question for the smart guys. 20' piece of 1" PVC

[Senior Citizen]

I've got quie a bit more rough sawn boards than I can store in 3 barns so I've having to improvise.

If I have a stack of lumber 5' high in center, 3' wide at the top,how far apart will I need to drive in my rebar stakes to make the pipe bend over the stack?

I'll be using 6 pipes to bend over and 1 on the crown and 1 on each side. All either taped strongly or zip tied firmly. I'm going to have to make at least two home made quansett huts for a while. Will be covering the frames with poly tarps.

Tks in advance for answers, suggestions or tips,
SC

I'm not sure PVC will bend that much to form a half circle, do you not want to cut it and use the proper fittings to build a frame? You could build an A-frame out of 2x4s for not much money that would probably be sturdier.

trial and error

Get a clear space to work in. Drive one piece of rebar into the ground to a depth you think you need to anchor the pvc. slide the pvc over the rebar and start to bend. When you reach the breaking point or close to it, you will have a basic starting point to work from. kind of like 0,0,0.

I think trying to figure out the physics of bending a piece of pvc will just have to many variables. i.e. tempurature, wall thickness, formulation of the pvc plastics, etc.

Just bend it and see what happens!

Why not use 3/4"? Are you using #6 rebar,or smaller?

I probably will use 3/4, just typed in one inch cause it was faster. Not sure about the rebar number, but I'm guessing 2' of 1/2 or 3/8 should be sufficent.

I can't find any schedule 20. I've bent 20' stick of that into the back of my truck many times and it was horshoe shaped and not a half circle..

I'll drive me a "stob" in the ground and give it a whirl.

Thanks guys. I just wanted to test the minds of or physics and math experts this morning.

If the PVC will bend cleanly into a semicircle, the ends will be about 13' apart.

If the PVC doesn't want to bend that far, you might try massaging it with a heat gun, a technique that works on a lot of plastics (but not necessarily all).

Figure on replacing those tarps about every year or so (maybe longer if they never have to bear any snow load), due to UV.

Drive galvy pipe in the ground where the rebar will go, 3/4" PVC will bend that far easy in warm weather,
Good luck

I've bent 3/4"x20', sch. 40 into the bed of a full sized pickup...Just don't leave it bent too long... It'll take a set...
Good luck,

Cut the pipe in half and add a 45 degree connector at the top.
